Does Daze interrupt foes that are immune to hard CC like Stun, Daze, Knockdown etc, via the Defiant buff?
The Daze duration is zero, that for sure, but I know a Thief that claims that his Tactical Strike does interrupt Champions nevertheless.

And please, don't just post "Well, they are immune to hard CC so Daze will do nothing", only answer if you know for sure that the game behaves like the tooltip descriptions indicate or not.
